CARPET-SWEEPER.

Application filed January 23, 1920.

To all whom it may concern:

Be it known that I, TOM DICKINSON, a British subject, residing at Accrington, county of Lancaster, England, have invented certain new and useful Improvements 1n Carpet-Sweepers, of which the following is a specification.

This invention relates to carpet sweepers, and is designed to prevent hairs, threads or other raveling materials from entangllng the extreme end tufts of the rotary brush and winding around the necks and pivots of the brush.

It consists essentially in applying to the end frame of the sweeper case appliances such as clips or brackets with serrated members to lie against or in close proximity to the brush neck, to cut and prevent any hairs, threads or the like wrapping around the brush neck or around the brush pivots, and with serrated members to engage the extreme end tufts of the brush to cut or dis engage any hairs, threads or the like that may entangle with the tuft.

The invention will be fully described with reference to the accompanying drawings.

Figure 1 is a plan of carpet sweeper partly in section viewed from the underside.

Fig. 2 is a sectional end elevation of carpet sweeper.

Fig. 3 is a perspective view of the clearer appliance removed from the sweeper.

Fig. 4 is a perspective View showing a modified form of the clearer appliance.

The appliance is in the form of a clip or bracket A of such a shape as may be readily attached to the end frame 5 of the sweeper case B (one at each end). It is preferably of the shape shown in Fig. 3 with two members a a to fit over the end frame 6, or it may be in a plurality of parts a a a as in Fig. 4, each part to be separately attached to the end frame.

Qne member a is attached to or fits over the inside of the end frame Z) of the case B, and the member a is attached to or fits over the outside of the end frame 6 of the case B covering the slot or opening I) through which the brush neck projects.

The member a is provided with project ing members oZ so disposed as to enter the extreme end tufts e of the brush E, and these are serrated or formed with a T end to catch and cut the hairs or threads which Specification of Letters Patent.

collect on these tufts of the brush. The member a is providedwith a serrated member d disposed at right angles and projecting inward to lie against the neck of the brush, and catch or cut any hairs or threads that may pass over the tufts toward the brush neck, and also prevents any hairs or threads reaching the brush pivots.

The extended projecting members a? may also serve as stops for the dust pans F, to prevent them opening too far.

WVhat I claim as my invention and desire to protect by Letters Patent is 1. In a carpet sweeper the combination with the end frame of the sweeper case and rotary brush, of an appliance attached to the sweeper case end frame and provided with serrated projecting member to lie against and engage the neck of the brush to catch and cut any hairs or threads that may collect thereon substantially as described.

2. In a carpet sweeper, the combination with the ends of the sweeper case and rotary brush of an appliance attached to the sweeper case ends comprising interior and exterior members, the interior member provided with projecting members to engage the end tufts of the rotary brush, and the exterior member provided with a serrated member disposed at right angles and projecting inward to engage and cut any hairs or threads on the brush neck.

3. An appliance for attachment to the end frame of carpet sweeper to prevent the lapping of hairs or threads around the brush neck, comprising a member to'attach to the end frame and a serrated member projecting at right angles therefrom to lie against the brush neck substantially as described.

l. A11 appliance for attachment to the end frame of carpet sweeper to prevent the lapping of hairs or threads around the brush neck and to clear the end tufts of the rotary brush, comprising a member to attach to the outside of the and frame of the sweeper case provided with a serrated projection to lie in contact with the brush neck, in combination with a member to attach to the inside of the end frame of the sweeper case provided with serrated projections to enter the the brush neck to prevent the Wrapping of my hand in presence oftwo subscribing Withairls) or threads around the brush neck in nesses this 5th of January, 1920. com ination with means to engage the extreme end tufts of the brush to cut and ree DICKINSON 5 move threads and hairs therefrom substan- Witnesses:
